VW'LW am i "BY Patented May 8, 1951 UNITED STATES PATENT OFFICE vEmoLE WHEEL Charles S. Ash, Milford, Mich. Application July 19, 1945, Serial No. 605,988 9 Claims. (01. 301-6) The present invention relates to vehicle wheels and more particularly to such wheels adapted to carry a plurality of road engaging tires.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

Theaccompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawings:

Fig. 1 is a side elevation of a vehicle wheel embodying the present invention viewed inwardly;

Fig. 2 is a cross sectional view taken along line 2-2 of Fig. 1;

Fig. 3 is a cross sectional view taken along line 3-3 of Fig. 1;

Fig. 4 i a cross-sectional view to the center line of the wheel of a modified embodiment of the present invention; and a Fig. 5 is a cross-sectional view to the center line of the wheel of a third embodiment ofthe present invention.

It is an object of the present invention to provide a safe and sturdy vehicle wheel of a type suitable for heavy duty work designed to carry a plurality of road engaging elements as, for instance dual pneumatic tires. Another object is the provision of such a wheel which is more simple in construction and more economical to fabricate than conventional vehicle wheels for comparable uses.

Referringin detail to the illustrative embodiments of the invention shown by way of example in the accompanying drawings, and referring first to the embodiment shown in Figs. 1 to 3, the wheel of the present invention is adapted to be mounted on the reducedend or spindle Ill of a vehicle axle II. As shown in Fig. 2, inner and outer roller bearings I2 and I3 respectively are mounted on suitable finished seats on the spindle I0 serving to freely rotatably mount the hub I4 of the wheel.

The wheel hub i formed, for greater facility and economy in fabrication, of an outer elongated substantially cylindrical portion l5 and an inner shorter portion [6, the latter portion having integrally formed therewith an outer radially extending flange ll which serves as a brake drum anchor as well as a support for other portions of the wheel, as will be pointed out. The portion I6 of the hub has a flared or enlarged place I8 at the outer-end of its central bore to accommodate a circular line of welding I9 of substantial size which securely joins the hub portions I5 and I6 together.

The inner race of bearing I2 seats against an annular ring 22 which in turn abuts against a shoulder 23 on the axle II preventing inward movement of the wheel assembly. The outer race of bearing I2 seats against the end of hub portion l5. The outer race of the outer bearing I3 seats against a shoulder 24 of the hub portion I5, and the whole assembly is maintained in place by a nut 25 on the end of spindle I0. Braking means for the wheel comprise a cylindrical brake drum 30 at the inner side of the wheel assembly having a circumferential flange 3| about midway of its width on its outer surface. A connecting element 32 is provided secured at its inner end to flange 3| of the brake drum, and at its outer end of greatly reduced diameter to the flange ll of hub I4. The central anchorage for the brake drum 30 prevents bellmouthing of the drum when excessive heats are generated, and the element 32 serves to dissipate brake drum heat before it is conducted in substantial amount to the vehicle wheel.

The vehicle whee] proper comprises an inner and an outer

prefabricated web

35 and 36 respectively secured to the hub I4 and adapted to demountably mount pneumatic tire rims on their outer peripheries. As best shown in Fig. 2, the inner web 35 has an outwardly axially turned portion 3! at its inner periphery which is seated on an outer finished surface of hub portion I5 and is securely welded thereto by a circular weld. Immediately radially outwardly of portion 31 of inner web 35 the web has a substantially plane portion normal to the axis of the wheel, which seats firmly against the outer side of flange ll and is held thereto by bolts 39, which likewise secured element 32 to the flange. Radially outwardly of the plane portion web 35 is formed with an outwardly flaring or enlarging frustoconical portion, and then is reversely turned in another frusto-conical portion which extends axially inwardly of the wheel assembly. At the intersection of the frusto-conical web portions just described there is formed a curved annular projection "is of the web 35, against which a similar portion of the outer web 36 abuts, as will hereinafter be described. The outer periphery of web 35 is axially inwardly turned to provide a substantially cylindrical seat ll for the turned edge or bead 42 of a conventional pneumatic tire rim 43. Axially inwardly the seat M is outwardly radially flared to provide an inclined seat 44 against which the bead 32 also seats, preventing imier axial movement of the rim 43. At av plurality of spaced apart positions around the web 35 it is integrally formed in portions as indicated by numeral 16 which are inwardly axially offset in a curve from the main body of the web and formed with plane portions 4'! apertured to receive rim mounting bolts 48 and seating the heads of such bolts.

The outer web 36 of the wheel is formed similarly to the inner web, having an outwardly turned cylindrical portion 50 at its inner periphery which seats on a finished outer surface of hub portion l and is securely welded thereto by a circular weld 5|. Radially outwardly of portion 53, the web has a frusto-conical portion inwardly axially extending; and the web is then abruptly turned to form another frusto-conical portion extending axially outwardly. The frusto-conical portions just described merge centrally of the web body to form an annular projection 52 at the inner side of the web which abuts the projection 40 of the inner web 35. The webs are securely joined together at these projections by an external circular line of welding 53, formin a strong, easily fabricated and assembled composite vehicle wheel body.

At its outer periphery the web 36 has an outwardly axially extending cylindrical portion 54 to seat a tire rim 55 which is preferably a duplicate of rim 43 but oppositely positioned. At a plurality of places around the web 36, corresponding to the places 46 of the inner web, it is similarly formed with integral outwardly axially curved portions 56 turned to provide plane portions 51 which are apertured to receive the outer ends of bolts 48. Integral web portions 58 lie at either edge of plane portions 51 joining the latter to the cylindrical periphery 54. Within each open ended rectangular box formed by the web portions 58 there are provided a pair of plates 68 securely welded together in the form of a V and extending axially inwardly to the plane portion 51 of the outer web. These members are welded, as shown in Fig. 1, to the under surface of cylindrical peripheral portion 54 of the web, and at their vertices provide seat against which conventional lugs 6| may press. A cylindrical spacer ring 62 is provided between

tire rims

43 and 55, and it will be apparent that nuts 53 on the ends of bolts 48 securely hold the dual rim assembly in place on the webs and allow for disassembly when desired.

, As shown at the bottom of Fig. 2 of the drawings, the webs 35 and 33 at corresponding places are interrupted at their peripheries as indicated by numeral 65. As best shown in Fig. 1, inner and outer brackets 66 and 6'! respectively are welded across these spaces, and may serve as supports for the valve stems to be positioned in the spaces so that ready access may be had thereto.

A somewhat modified embodiment of the vehicle wheel of the present invention is shown in Fig. 4 of the drawings, the wheel comprising a one-piece tubular hub member Ill internally formed to receive roller bearings H and 12 whereby the hub is mounted for free rotation on the spindle in. This embodiment also comprises inner and outer webs l3 and 14 respectively, the inner web having an axially inwardly turned portion at its inner periphery securely welded on a finished outer surface of the hub 10, and the outer web having an axially outwardly turned inner peripheral portion likewise securely welded on a second outer finished surface of the hub.

As shown in Fig. 4, the inner web 13 flares radially outwardly in a frusto-conical portion nearer the hub, and is then reversely curved in an axially inwardly flaring frusto-conical portion to the outer periphery of the web. At this periphery the web is formed in an integral cylindrical portion 15 having a flared end 15, serving as a seat for a conventional tire rim H. In this embodiment of the invention the brake drum I3 for the dual wheel is connected by means of a cylindrical adapter to the radially inwardly turned portion 8| of the rim seat IE-16. The adapter 80 is securely welded to the web portion 81 as shown, and is connected by an end flange 82 to a centrally located flange 83 of drum [9 by means of suitable bolts.

The outer web 14 from its inner periphery flares axially inwardly in a frusto-conical portion and then is reversely curved in an axially outwardly directed frusto-conical portion, terminating in an outer peripheral cylindrical portion, 85. Similarly to the embodiment of the invention shown in Fig. 1', an inner web 13 of the embodiment of Fig. 4 is formed in a plurality of axially. inwardly curved portions 86 and the outer web is formed in a plurality of corresponding axially outwardly curved portions 81. Over the ends of the spoke formations formed by portions and B7 on the outer web 14 there are welded L-shaped plates to serve as seats for an outer rim 90 which may be a duplicate of rim i'l. Mounting bolts 9| extend through portions 86 of the inner web and through the downwardly extending reaches of plates 89, and lugs 92 and spacer ring 93 complete the demountable rim assembly.

It will be noted that the frusto-conical body portions of the inner web 13 which have been described merge centrally of the web in an annular projection 95 while the frusto-conical body portions of the outer web 14 merge in an annular projection 96. These projections in the assembled wheel are radially ofiset from each other, 96 being of smaller diameter than 95, so that the webs overlap and contact each other for a short radial distance before diverging from each other. The composite wheel is thusformed of mutually reinforcing parts, and the webs are securely welded together by a circular external welds].

In the embodiment of the invention shown in Fig. 5 of the drawings the hub assembly is similar to thatin the embodiment shown in the first three figures of the drawings, being comprised of a tubular portion I08 and a shorter inner end portion 101 welded thereto as at I02, the portion Hll having an integral flange I03. A conventional brake drum. H14 islsecu'red by bolts I05 to the flange I03.

The inner and outer webs I01 and I08 respectively are secured at their inner peripheries to the hub portion lllll similarly to th embodiment shown in Figs. 1-3, the inner web receiving support from the fiange N33. The webs then converge on each other overlapping along their central portions as indicated by the nume'ral Ill) and being'welded to each other. The webs then diverge to form rim seats, the formation being similar to that already described for the embodiment shown in Fig. 4. In this embodiment a plurality of plates III are welded to the spokelike formations of the outer web I08 and adjustment may be made by the welding operation in asuitable jig so that the plates are in exact axial alignment with the cylindrical rim seat H2 on the inner web I07.

It will be noted by those familiar with vehicle wheel construction that th present invention provides a heavy duty wheel of a strong integral web type which is adapted to mount dual tires on rims of a conventional type so that they are easily mounted and demounted. The wheel body and hub are formed of easily prefabricated component parts which are simply assembled, and, when so assembled, mutually reinforce one another providing great strength for the finished wheel.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.
